Subject: [PATCH 2/2] staging: rtl8723bs: Prevent duplicate NULL tests on a value

When a value has been tested for NULL in an expression, a
second NULL test on the same value in another expression
is unnecessary when the value has not been assigned NULL.

Remove unnecessary duplicate NULL tests on the same value that
has previously been NULL tested.
